Embodiment Construction

[0019] The video conferencing system of the present invention has the following functions: the local video conferencing terminal unit can obtain the video information of other video conferencing terminal units; A unit is a collaborative work client, and only one collaborative work client has collaborative work permissions. The collaborative work clients can obtain the desktop information of the collaborative work server, and the collaborative work clients with the collaborative work authority can realize the remote collaborative work of the collaborative work server.

[0020] figure 2 An example of the present invention is given. In this example, both the video conferencing terminal and the MCU are connected to the IP network and communicate through the IP network, and the collaborative work converter is connected to the video conferencing terminal through a serial port or a network port. The collaborative work converter is a PC, which can be built-in or externally installe...

Abstract

A built-in video conference cooperative operation system comprises a multi-point control unit and a plurality of video conference terminal units; in each video conference, only one video conference terminal unit is used as a cooperative operation server and other video conference terminal units are cooperative operation client terminals; furthermore, only one cooperative operation client terminalhas a remote operative authority simultaneously. The cooperative operation client terminal with the remote operation authority collects the control information of a keyboard and a Mouse, encodes the information and transmits the encoded information to the cooperative operation server by the multi-point control unit; the cooperative operation server receives and decodes the control information of the keyboard and the Mouse, thus obtaining the operation instruction of the Mouse and the keyboard executable by the computer. The system solves the problem that the computer screen stream of the existing video conference system can be watched only by a dual-stream function and the auxiliary-stream can not be used for cooperative operation, perfects the cooperative mode of the user for informationcommunication and improves working efficiency and quality.

Description

technical field [0001] The invention relates to the technical field of multimedia communication, in particular to a video conference system, in particular to an embedded video conference collaborative work system. Background technique [0002] With the development of the information society, the pure data communication method can no longer meet people's needs. People urgently need a multimedia interactive communication method integrating audio, video and data. It is against this background that multimedia communication technology has developed. a new technology. Through multimedia communication technology, we can carry out multimedia information exchange integrating pictures, sound, video, text and other media forms without being limited by time and space. The two parties in the communication can not only hear each other's voice, but also transmit data files. Even have face-to-face video sessions. Therefore, the emergence and development of multimedia communication technol...
